The Pure Iron Stamped Relay Yoke is a core component of relays in new energy vehicles, belonging to the field of electronic components and special materials. This component relies on electromagnetic attraction to control circuit continuity, while also providing heat dissipation and structural support. Its overall performance directly affects the relay's operational stability and service life. New energy vehicles operate under complex conditions, requiring these components to continuously withstand high-frequency operation and high-current loads, ensuring the safe operation of the entire vehicle's electrical system.
The Sheet Metal Relay Yoke, operating on the principle of electromagnetic attraction, has a clear operating logic and a scientifically designed structure. When a 9V trigger current is applied to the control electrode, the internal electromagnetic field drives the iron core to close and open the contacts. The main body of the component is made of pure electric iron, possessing high permeability and low remanence, effectively reducing energy loss during operation. Encapsulated in epoxy resin, it provides insulation, high-temperature resistance, and vibration resistance. The optimized iron core structure also ensures stable heat dissipation under a rated operating current of 15A.
Power Relay Yoke is widely used in the power management and motor control systems of new energy vehicles, commonly applied in critical areas such as battery charge/discharge switching and drive motor start/stop control. The product features a 50Hz operating frequency and a flexible operating design, reducing the impact force at the moment of contact closure, suppressing arcing, and mitigating component wear. Currently, it is available in both boxed and cartridge packaging, adaptable to different relay sizes and offering excellent universal compatibility.
In terms of overall performance, the Precision Relay Yoke Stamping Part offers significant improvements over traditional relay cores. It has a rated current-carrying capacity of 15A, and a 9V trigger current ensures precise control. Epoxy resin encapsulation allows the product to withstand temperatures from -40℃ to 125℃, sufficient for various complex outdoor and automotive environments. The snap-on mounting structure eliminates the welding process, improving assembly efficiency, and the unique buffer design extends the overall lifespan of the relay to more than 1.5 times that of traditional products.
To extend service life and ensure reliable operation, the Magnetic Yoke Metal Stamping for EV Relay must be installed and maintained according to specifications. During installation, ensure the iron core and coil axis are aligned to prevent misalignment and subsequent engagement failures. Maintain a clean operating environment to avoid metal dust affecting electromagnetic performance. Regularly check the contact oxidation level; minor oxidation can be easily treated with grinding, while severe wear necessitates immediate replacement. After prolonged periods of inactivity, it is recommended to perform several no-load tests to confirm component responsiveness.
